Vienna Symphonic Library

Headquarters of VSL at Synchron Stage Vienna

Vienna Symphonic Library GmbH (VSL) is a developer[1] of sample libraries and music production software for classical orchestral music. The company is located in a landmark protected building, called Synchron Stage Vienna based in the Austrian capital's 23rd district.

The Vienna Symphonic Library provides virtual instruments and the digital recreation of the acoustics of famous concert halls such as the Konzerthaus and the Große Sendesaal at Austrian Public Radio ORF's broadcasting house, both in Vienna, and the Sage Gateshead concert hall in England. The technique used is impulse response resulting in an authentic digital convolution reverb. The virtual instruments are based on digital samples of solo voices and instruments as well as orchestral ensembles. The VSL software acts as an interface for the music composer to play the real instruments on a MIDI keyboard.
